本研究调查了一种促进协调的潜在机制。在基于信念的学习模型的理论指导下，我们进行了一个多阶段、二元选择和最弱环节的实验室协调实验，以研究渐进性--随着时间的推移缓慢增加所需的贡献水平（赌注），而不是立即要求高水平的贡献--对群体协调绩效的影响。我们将受试者随机分配到三种治疗：从高赌注开始并继续，从低赌注开始但几段时间后跳到高赌注，从低赌注开始而随着时间的推移逐渐增加赌注（渐进性治疗）。我们发现，相对于其他两种治疗，在渐进治疗中，小组在高利害关系下协调最成功。我们还发现了支持基于信念的学习模型的证据。这些发现为促进成功的自愿协调指出了一个简单的机制。

英文摘要：
  This study investigates a potential mechanism to promote coordination. With theoretical guidance using a belief-based learning model, we conduct a multi-period, binary-choice, and weakest-link laboratory coordination experiment to study the effect of gradualism - increasing the required levels (stakes) of contributions slowly over time rather than requiring a high level of contribution immediately - on group coordination performance. We randomly assign subjects to three treatments: starting and continuing at a high stake, starting at a low stake but jumping to a high stake after a few periods, and starting at a low stake while gradually increasing the stakes over time (the Gradualism treatment). We find that relative to the other two treatments, groups coordinate most successfully at high stakes in the Gradualism treatment. We also find evidence that supports the belief-based learning model. These findings point to a simple mechanism for promoting successful voluntary coordination.
